The uncertainty of the extent of immunity in the case of visiting armed forces is illustrated by the varying language used by authorities upon international law: for example in Hall, International Law, 8th ed. (1924), p. 251, the learned author says: - "and it is believed that the commanders, not only of forces in transit through a friendly country with which no convention exists, but also of forces stationed there, assert exclusive jurisdiction in principle in respect of offences committed by persons under their command, though they may be willing as a matter of concession to hand over culprits to the civil power when they have confidence in the courts, and when their stay is likely to be long enough to allow of the case being watched." I call attention to the words "it is believed". See Pitt Cobbett to the same effect - Leading Cases on International Law, 5th ed. (1931), vol. 1, p. 274. Woolsey, Introduction to the Study of International Law, English edition reprinted from the fourth American edition, (1875), p. 67, quotes Vattell (iii. 8, s. 130) - "the grant of passage includes that of every particular thing connected with the passage of troops, and of things without which it would not be practicable - such as the liberty of carrying whatever may be necessary to an army; that of exercising military discipline on the officers and soldiers; and that of buying at a reasonable rate anything an army may want, unless a fear of scarcity renders an exception necessary, when the army must carry with them their provisions." The learned author continues - "If we are not deceived, crimes committed along the line of march, away from the body of the army, as pilfering and marauding, authorise arrest by the magistrates of the country, and a demand at least that the commanding officers shall bring such crimes to a speedy trial. When the transit of troops is allowed, it is apt to be specially guarded by treaties." Here again the words "If we are not deceived" show an absence of certainty in the statement of the rule. See also Travers Twiss, The Law of Nations, 2nd ed. (1884), Rights and Duties in Time of Peace, p. 271, where the following statement is made: - "if an Independent Power permit the armed forces of another Nation to pass through its territory, this permission implies a waiver on its part of all jurisdiction over the troops during their passage through its territory, and a licence to the commander to maintain that discipline, and to inflict those punishments, which the government of his troops may require." It will be observed that the extent of the licence does not correspond with the extent of the waiver. Such a rule would either make no provision, or at least would leave doubtful what authority could act, in the case of wrongful interference by a member of the armed forces with civilian inhabitants. There might be interference with civilian inhabitants which was wrongful according to local law, but which would not affect the discipline or government of the troops as troops. Accordingly, the licence to the commander to which reference is made would not authorize action by the commander in such a case, and yet it is said that there is a waiver of all jurisdiction by the civil power over the troops.
